TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vehicle armrest structure.
[0002]
[Prior art]
The inner side wall panel in the vehicle interior is formed by a door inner panel where there is a door, and is formed by an inner panel of the vehicle body where there is no door. A side trim as an interior material is attached to such an inner wall panel from the vehicle interior side. The side trim is provided with an armrest support portion protruding toward the vehicle interior and formed integrally with or separate from the side trim. A substantially horizontal armrest body is provided on the upper surface of the armrest support portion, and the occupant's arm can be placed on the armrest body.
[0003]
The armrest body must originally have high rigidity as a whole so as to withstand the load applied from the occupant's arm. On the other hand, in the event of a side collision of the vehicle, the armrest body hits the vicinity of the waist of the occupant, so that it is required to have a function of easily crushing and absorbing collision energy. For this reason, conventionally, a shock-absorbing portion (fragile portion) that is easily deformed is provided in a part of the armrest body (for example, see Patent Document 1).

[Problems to be solved by the invention]
However, in such a conventional technique, since an impact relaxation portion (fragile portion) is provided in a part of the armrest main body, an essential portion of the armrest main body necessary for securely supporting the occupant's arm is provided. Ensuring rigidity, a function, was sacrificed.
[0006]
The present invention has been made by paying attention to such a conventional technique, and provides an armrest structure for a vehicle that can achieve both the securing of the rigidity of the armrest body and the collision energy absorbing performance.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, a side trim is attached to the inner wall panel of the vehicle body from the vehicle interior side, an armrest support portion protruding toward the vehicle interior is formed on the side trim, and an armrest body is provided above the armrest support portion. An armrest structure for a vehicle, wherein a metal support bracket is provided inside the armrest support portion, the upper portion of which is fixed near the lower portion of the armrest body and the lower portion is fixed to be close to the inner wall panel, When the support bracket receives a load from the vehicle cabin side, the support bracket has a cross-sectional shape that is deformed so as to be displaced upward.
[0008]
According to a second aspect of the present invention, the upper portion of the support bracket is offset from the lower portion toward the vehicle interior via the lateral surface portion, and the lateral surface portion is inclined upward from the horizontal toward the vehicle interior side. It is characterized by the following.
[0009]
The invention according to claim 3 is characterized in that at least one of the lateral surface portion and the upper portion of the support bracket is set near a height position corresponding to the iliac of the occupant's waist.
[0010]
The invention of claim 4 is characterized in that a handle bracket for a pull handle is provided between the support bracket and the armrest body.
[0011]
【The invention's effect】
According to the first aspect of the present invention, the armrest main body does not need to be provided with a fragile portion as in the related art, so that the rigidity, which is an essential function of the armrest main body, can be sufficiently ensured. Further, even when the armrest body is made highly rigid as described above, since the support bracket has a cross-sectional shape that is deformed so as to be displaced upward when the support bracket receives a load from the vehicle interior side, When a side collision of the vehicle causes the armrest body to hit the vicinity of the occupant's waist and a load acting as a reaction from the occupant's body, the armrest body to which the upper part of the support bracket is fixed is lifted upward, and the armrest body is moved from the armrest support section. Detach or rotate. Therefore, even if the armrest body itself has high rigidity, the entire armrest structure is easily crushed, and the collision energy can be reliably absorbed to protect the occupant.
[0012]
According to the second aspect of the present invention, since the lateral portion of the support bracket offset toward the vehicle interior is inclined upward from the horizontal toward the vehicle interior, a load from the vehicle interior is applied. Then, the lateral surface portion rotates upward about the fulcrum on the vehicle outside, and the upper portion of the support bracket can be lifted upward. The support bracket is easy to manufacture because of its simple cross-sectional structure.
[0013]
According to the third aspect of the present invention, at least one of the lateral surface portion and the upper portion of the support bracket is set in the vicinity of the height position corresponding to the most protruding iliac in the skeleton of the occupant's waist. When the vicinity of the waist hits the armrest main body, the load can be transmitted to the support bracket from the iliac bone at an early stage and deformed.
[0014]
According to the invention of claim 4, since the handle bracket for the pull handle, which is a high-rigidity component, can be lifted together, the armrest structure can be reliably crushed even with the handle bracket.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes a front door on the right side of an automobile. A door trim 3 made of resin as a "side trim" is attached to a door inner panel 2 as an "inner wall panel" from the vehicle interior side. A pocket trim 4 is attached to a lower portion of the door trim 3 from the vehicle interior side, and a pocket portion 5 for storing small items is formed there.
[0016]
An armrest support 6 is attached to the door trim 3 so as to protrude toward the vehicle interior. Embossed portions 7 and 8 are formed vertically on the back surface of the armrest support portion 6. The door trim 3 located inside the armrest support portion 6 has three openings 9 in the front-rear direction. The door inner panel 2 exposed in the opening 9 is supported by the support bracket 11 via the reinforcing panel 10. The handle bracket 12 and the handle bracket 12 are fastened together by fastening means 13 in close proximity.
[0017]
The handle bracket 12 is sandwiched between the support bracket 11 and the door inner panel 2, and a bent portion 15 corresponding to the pull handle concave portion 14 formed in the door trim 3 is formed at an upper portion. The armrest body 16 is attached to the upper portion of the handle bracket 12 so as to cover the upper portion of the armrest support portion 6. The armrest body 16 is also separated from the concave portion 14 together with the upper portion of the handle bracket 12, and is used as a pull handle when the front door 1 is closed by hanging a hand put in the concave portion 14 on the bent portion 15 of the handle bracket 12. it can.
[0018]
The support bracket 11 has a crank-shaped cross section in which an upper portion 18 is offset close to a lower portion of the armrest main body 16 on the vehicle cabin side via a lateral surface portion 19 with respect to a lower portion 17 fastened together with the handle bracket 12. The embossed portion 7 on the upper side of the armrest support portion 6 is fixed to the upper portion 18 of the support bracket 11 by fastening means 20, so that the overall strength of the armrest support portion 6 is secured. The armrest main body 16 mounted on the upper part of the armrest support portion 6 has a substantially U-shaped cross section, and a rib 21 is also formed on the back surface, so that the armrest main body 16 itself has a very high rigidity structure. ing.
[0019]
That is, the armrest main body 16 of this embodiment does not need to form a fragile portion that is easily deformed as in the related art, so that the rigidity, which is an essential function of the armrest main body 16, can be sufficiently ensured. Therefore, the occupant's arm placed on the armrest body 16 can be reliably supported.
[0020]
An upper portion of the handle bracket 12 is located below the armrest body 16, and an upper portion 18 of the support bracket 11 is located further below the armrest body 16. That is, the upper portion of the handle bracket 12 is vertically sandwiched between the armrest main body 16 and the support bracket 11.
[0021]
In the support bracket 11 of this embodiment, the lateral surface portion 19 located in the middle thereof is not horizontal, but is inclined upward by a predetermined angle θ toward the vehicle interior. Further, the lateral surface portion 19 and the upper portion 18 of the support bracket 11 are set in the vicinity of a height position corresponding to the iliac 23 (see FIG. 3) in the general occupant waist 22. The ilium 23 is the portion of the skeleton of the occupant's waist 22 that protrudes most left and right.
[0022]
Therefore, when the armrest support portion 6 and the armrest body 16 are displaced toward the occupant's waist 22 in a side collision of the vehicle, the support bracket 11 inside the armrest support portion 6 contacts the iliac 23 which protrudes to the left and right early, and A load F as a reaction can be applied to the upper portion 18 and the lateral surface portion 19 of the support bracket 11 from the bone 23 side.
[0023]
When such a load F is applied to the support bracket 11 from the occupant side, the side surface portion 19 of the support bracket 11 is in a state of being inclined upward toward the interior of the vehicle. The support bracket 11 rotates upward around the outer fulcrum, and the vertical dimension of the entire support bracket 11 is deformed so as to expand while the lower portion 17 fastened to the door inner panel 2 is fixed.
[0024]
Therefore, the armrest support 6 to which the upper part 18 of the support bracket 11 is fixed is lifted upward, and the armrest main body 16 is detached from the armrest support 6 or rotated, so that the armrest main body 16 itself has high rigidity. Even if there is, the entire armrest structure including the armrest body 16 and the armrest support portion 6 is easily crushed, and the collision energy can be reliably absorbed to protect the occupant.
[0025]
A handle bracket 12 for a pull handle, which is a high-rigidity component, is also provided below the armrest main body 16. The handle bracket 12 can also be lifted together by the upper portion 18 of the support bracket 11 that rises. Therefore, even if the handle bracket 12 is provided, the armrest structure can be reliably crushed.
[0026]
In the above-described embodiment, the example in which the separate armrest support portion 6 is attached to the door trim 3 has been described. However, the armrest support portion 6 integrally formed with the door trim 3 may be formed. Further, the formation of the armrest support portion 6 is not limited to the door trim 3, but may be formed as a "side trim" attached to a vehicle body inner side wall panel other than the door from the vehicle interior side.
